question\ncombine like terms.\n$2x^2 + 7 + 6x - 1 - 7x - 6x^2 + 1$

Explanation:

Step1: Group like terms

Group (x^2) terms, (x) terms, and constant terms:
((2x^2 - 6x^2) + (6x - 7x) + (7 - 1 + 1))

Step2: Combine (x^2) terms

(2x^2 - 6x^2 = (2 - 6)x^2 = -4x^2)

Step3: Combine (x) terms

(6x - 7x = (6 - 7)x = -x)

Step4: Combine constant terms

(7 - 1 + 1 = 7)

Step5: Combine all results

(-4x^2 - x + 7)

Answer:

(-4x^2 - x + 7)
